We have had more difficulties with phosphate levels being higher this year, and it was much hotter, so we had more yellow algae issues.
We have used liquid phosphate removers in the past, so I wasn’t getting
the same performance this year. When I put a PhosLocker in, within a week or two the pools were all cleared up and looking great!
I love them, they are so easy to use and I don’t have to clean the filter afterwards.
A yellow algae bloom costs a lot to kill, so using PhosLocker saves money.

PhosLocker, like other phosphate removal products, does not replace the need for standard disinfection products, but it can work synergistically with any type of disinfection system in the market today.  Daily, even hourly variations in disinfectant levels can create a situation where algae has a chance to thrive and the expense of killing an algae bloom is significantly more than a preventive product like PhosLocker.  Use PhosLocker as a simple layer of protection to keep pool water clean.  


PhosLocker is the CLEAR choice in Phosphate removal.
